“…Despite the fact that researchers defined normative values for taekwondo athletes across their countries (Malacko et al, 2015;Jeon et al, 2020), not one study included official weight categories but only chronological age. When taking into consideration the official weighing system, this is not of great importance, because it can be assumed that differences between categories exist.…”

Elite Croatian Junior Taekwondo Competitors: Morphological Characteristics and Body Composition Reference Values

2021

The main purpose of this study was to determine the body composition and anthropometric reference values of male and female junior Croatian taekwondo competitors according to official weight category. Additional aim of the study was to identify possible differences in variables between the weight categories. The sample comprised 247 junior participants of the national taekwondo championships divided into male (N=121) and female (N=126). The variable sample was defined by a set of 8 measurements: Body height (cm), Body mass (kg), Body mass index, Body fat (%), Body fat (kg), Muscle mass (kg), Lean body mass (kg) and Total body water (%). Results confirm previous studies proving that younger taekwondo practitioners have higher levels of body fat than their more experienced peers (seniors). Significant differences were only found between lean and heavy categories. Male junior taekwondo athletes show total body water percentages from 57.4 to 74.8 %, with significantly lower percentages in higher weight categories, while female athletes in heigher categories demonstrate a worrying level of hydration status, therefore endangering their performance and overall health. As the first paper that investigates the reference values of junior taekwondo athletes but based on official weight categories it is especially important as each weight category warrant different body composition requirements, as seen from significant differences across different variables. Future studies should include motor abilities inspection throughout the weight categories and possible use of calculation of metabolic age.

“…e second is postshot throw and level-ten stepping, which reflect the unique strength qualities of sprint athletes, the continuous explosive ability of the lower limbs, and the strength of the upper limbs. In addition, they also reflect the upper and lower limb coordination ability and power chain transmission ability [20]. e third is the sprint test (30 m, 60 m, and 100 m), which reflects the subjects' starting ability, acceleration ability, and sprint conversion ability.…”

This work is to develop an effective trunk support stability training program, thereby improving the quality of college physical education. First, the advantages and characteristics of trunk support stability training are analyzed under the physiological basis and biomechanical basis of trunk support stability training. Then, the trunk support stability training program is developed to train the stability, strength, and balance of the sprint athletes’ shoulder, trunk, and buttocks musculature, as well as the control ability of the limbs. Twenty undergraduates in the track and field sprint special class of Xi’an Physical Education University are recruited and rolled into experimental group and control group, each with 10 students, and trained for 8 weeks. Finally, functional movement screen (FMS), postshot throw, level-ten stepping tests, and sprint tests (30 m, 60 m, and 100 m) are performed. The results show that before the start of the experiment, there is no considerable difference in the score comparison between experimental group and control group in different test items ( P > 0.05). After the experiment, the test scores of level-ten stepping, postshot throw, and 30 m, 60 m, and 100 m sprint of experimental group are remarkably different within the group ( P < 0.05). In addition, the level-ten stepping and 60 m and 100 m sprint scores of experimental group and control group have great differences between the groups, indicating that the trunk support stability training program formulated in this work has a notable effect on college physically educated students.

“…Although it is crucial to test these characteristics, research has shown that medalist and non-medalist elite taekwondo athletes in the European championships do not differ in terms of anthropometric and body-composition components and have a similar profile [ 3 ]. As with previous ones, other studies have also investigated body composition in elite taekwondo athletes [ 4 , 5 , 6 , 7 ], but only a few of them were conducted based on weight categories [ 8 , 9 , 10 ]. Research that permits information about the body composition of top athletes solely based on chronological age does not provide a thorough insight into the actual situation in different weight categories and, thus, prevents the adjustments of training programs for each category individually.…”

This study examines the maturity status and relative age effect in elite youth taekwondo Croatian National Team athletes. Measurements of biological age, maturity offset, and body composition were taken from a sample of 17 junior athletes. Differences in maturity status were observed among athletes of the same chronological age, with variations in sitting height and age at peak height velocity. Male athletes generally exhibited higher values in body height, percentage of body fat, muscle mass, and total body water. No significant relative age effect was found. These findings highlight the importance of considering individual biological age and maturity status for talent development and training program adjustments. Further research involving athletes from different countries is recommended to validate these results and enhance the understanding of youth taekwondo athlete development.
